Question: A bridge is being constructed across a river. The bridge is to be supported by two cables, each anchored on opposite sides of the river

A bridge is being constructed across a river. The bridge is to be supported by two cables, each anchored on opposite sides of the river and attached to the bridge at points 100 meters apart. The cables are to be anchored at points on the same side of the river, 80 meters apart. If the point where the cables are attached to the bridge is 20 meters above the water and the point where they are anchored is 60 meters above the water,

find the lengths of the cables and their angles of inclination with respect to the horizontal. Assume that the river is straight and 120 meters wide.
